PsiQuantum IPO

PsiQuantum is developing a fault-tolerant quantum computer using a photonic approach, which differs from the superconducting and trapped-ion methods used by most competitors. The company's architecture relies on photons as qubits and silicon photonic chips manufactured using existing semiconductor fabrication processes, potentially offering advantages in scalability and operating temperature requirements.

The company claims to be building the first commercially viable quantum computer capable of solving real-world problems that are intractable for classical computers, targeting applications in pharmaceuticals, materials science, and financial modeling. PsiQuantum has partnered with GlobalFoundries for manufacturing and aims to achieve quantum advantage with a million-qubit system, significantly larger than current quantum computers.
